CHECKWEIGHER

摘要

The present invention discloses a checkweigher comprising a conveying belt (1,1a)for conveying an object. The checkweigher comprises an object shape recognition apparatus for detecting and recognizing information about the shape of a contact surface between the object conveyed on the conveying belt (1,1a) of the checkweigher and the conveying belt (1,1a) and information about the position of the object on the conveying belt (1,1a). The checkweigher further comprises a calculation unit for querying or calculating a correction parameter with the information about the shape and the information about the position of the object on the conveying belt (1,1a), and correcting the weight of the object obtained by the checkweigher with the correction parameter. By means of the present invention, weighing data is compensated and corrected by recognizing the dimension of the object on the conveying belt(1,1a) and the position thereof on the conveying belt (1,1a), to remove impact of the detected object on dynamic weighing, thereby improving the weighing precision.
